X–IG® – Visual Image Generator

CATI Training Systems′s image generator systems are the ideal choice for the visualization of simulation training systems. For over twelve years, CATI Training Systems has been providing unparalleled rendering performance through advanced software algorithms and optimizations.

CATI Training Systems′s X–IG® image generator is a Commercial off the Shelf (COTS) product for PC–based visual simulations. X–IG® is specifically designed around industry standard OpenGL®, a high performance graphics Application Programming Interface (API), and OpenFlight, the 3D standard format for the visual simulation industry.

X–IG® is designed to render real–time Out–the–Window (OTW) and sensor scenes for training and simulation, creating real–world high resolution photorealistic visual and sensor scenes. X–IG® includes complete physics–based modeling for atmospheric, NVG, DTV, and IR simulations. X–IG® additionally includes special effects which complement the image generator enhancing scenes.
